adi_driver

This package contains ROS driver nodes for Analog Devices(ADI) sensor products mainly communicate by SPI(Serial Periferal Interface).

Currently supported devices are:

• ADIS16470
  • Wide Dynamic Range Mini MEMS IMU
• ADXL345:
  • 3-Axis, ±2 g/±4 g/±8 g/±16 g Digital Accelerometer
  • The support for this device is experimental
• ADIS16495
  • Higher grade MEMS IMU
  • The support for this device is experimental

You need a SPI interface on your PC to communicate with device. This package supports Devantech’s USB-IIS as the USB-SPI converter.

USB-IIS

Overview

USB-IIS is a USB to Serial/I2C/SPI converter, simple, small and easy to use. You don’t need any extra library like libusb or libftdi. The device is available on /dev/ttyACM* as modem device.

Please consult the product information and SPI documentation for the detail.

Tips

You need to remove the jumper block on Power link pins to provide 3.3V for the device.

You need to add your user to dialout group to acces /dev/ttyACM* .

``` $ sudo adduser your_user_name dialout

If it takes several seconds until /dev/ttyACM* available, you need to
uninstall modemmanager as:


``` $ sudo apt remove modemmanager 

ADIS16470

Overview

ADIS16470 is a complete inertial system that includes a triaxis gyroscope and a triaxis accelerometer.

You can use Breakout board for easy use.

Connection

You need to build a flat cable to connect the USB-ISS and the ADIS16470 breakout board. The picture shows a implementation.

Very simple schematic is here. J1 is the USB-ISS pin and J2 is the 2mm pin headers on the ADIS16470 breakout board.

Note: you only need to connect one of the power-line(3.3V and GND). They are connected in the breakout board.

BOM

• J1: 2550 Connector 6pin
  • Available at Akiduki
• J2: FCI Connector for 1.0mm pitch ribon cables
  • Available at RS Components
• 1.0 mm pitch ribon cable
  • Available at Aitendo
